Title:
HEAT PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2023046527
Kind Code:
A
Abstract:
To provide a heat processing device in which the overall configuration of the heat processing device capable of forming a swirling flow for cooling a workpiece may be shortened, components for forming a swirling flow in a cooling tank may be manufactured in a simple structure, and the components for forming the swirling flow may be easily installed in the device.SOLUTION: A heat processing device 1 is equipped with a cylindrical cooling tank 13 in which a workpiece 10 is placed, and an introduction tube 14 for introducing a refrigerant into the cooling tank 13 for a heat treatment of the workpiece 10. The introduction tube 14 includes a conversion member 21 that changes the direction of the flow of the refrigerant at an end of the side connected to the cooling tank 13 and forms a flow of the refrigerant swirling along the circumferential direction of the cooling tank 13. The conversion member 21 extends along the longitudinal direction of the cooling tank 13 between the bottom and top sides of the introduction tube 14, and has a curved surface (25a, 26a, 27a) along the inner shape of the cooling tank 13 as viewed from the longitudinal direction of the cooling tank 13.SELECTED DRAWING: Figure 2
